Description

Technical Field

[0001] This invention relates to the field of concrete pouring, specifically to a prefabricated building concrete pouring device. Background Technology

[0002] Concrete casting refers to the process of mixing cement as the main binder with water, sand, and gravel, and, when necessary, chemical admixtures and mineral admixtures, in appropriate proportions, followed by uniform mixing, compaction, molding, and curing to create artificial stone. During the casting of high-rise buildings and bridge piers, the high free fall can easily cause concrete segregation, resulting in exposed reinforcement and honeycombing after solidification. Furthermore, uneven concrete distribution often occurs during casting, leading to unsatisfactory casting results and uneven concrete distribution.

[0042] Reference Figures 1-5 The present invention provides a technical solution: a prefabricated building concrete pouring device, comprising:

[0043] A connecting seat 1, a housing 2 fixed on the connecting seat 1, an isolation bucket 3 fixed on the housing 2, and symmetrically opened sliding grooves 9;

[0044] Mounting frame 4 is fixed on the housing 2 and forms a material conveying bin with the isolation hopper 3. A drive bin is also provided on the mounting frame 4.

[0045] The conversion mechanism 5 is fixed inside the drive compartment;

[0046] The discharge mechanism 6 is installed inside the housing 2 and is connected to the conversion mechanism 5 and the adjustment mechanism 7.

[0047] Adjustment mechanism 7 is symmetrically fixed at the bottom of housing 2; and

[0048] The spiral conveyor rod 8 is rotatably installed inside the material hopper, and a small pulley is fixed at the part that passes through the drive hopper. The small pulley is driven by the conversion mechanism 5.

[0049] In a preferred embodiment, the conversion mechanism 5 includes:

[0050] Motor 51 is fixed inside the drive compartment, and a large pulley is fixed on the output shaft of motor 51. The large pulley and the small pulley are driven by a belt.

[0051] The conversion housing 52 is fixed inside the drive compartment; and

[0052] The converter 53 is rotatably installed inside the converter housing 52, with one end near the large pulley fixed to the output shaft of the motor 51 and the other end connected to the discharge mechanism 6.

[0053] It should be noted that starting the motor 51 will cause the screw conveyor 8 to begin conveying the concrete, and the concrete will be mixed a second time during the conveying process to prevent segregation of the concrete when it falls from a height. Finally, the concrete will fall into the discharge mechanism 6, and the discharge mechanism 6 will make the concrete fall evenly under the action of the converter 53.

[0054] In a preferred embodiment, the converter 53 includes:

[0055] The bevel gear 531 has one end face fixed on the output shaft of the motor 51;

[0056] A second bevel gear 532 is symmetrically and rotatably mounted on the conversion housing 52 and meshes with a first bevel gear 531.

[0057] The third bevel gear 534 is rotatably mounted on the conversion housing 52 and meshes with the second bevel gear 532. A second drive shaft 535 is fixed through the third bevel gear 534 near the end face of the discharge mechanism 6. The second drive shaft 535 has a hollow channel inside.

[0058] A drive shaft 533 is rotatably mounted within the channel, with one end fixed to the other end face of the bevel gear 531, and the other end fixed to a rotating wheel 536. Multiple pins are fixed circumferentially around the rotating wheel 536.

[0059] Rotary wheel 537 is fixed on the transmission shaft 535 and has multiple pins fixed around its circumference.

[0060] It needs to be explained that during operation, the action of bevel gear 1 (531), bevel gear 2 (532), and bevel gear 3 (534) causes drive shaft 1 (533) and drive shaft 2 (535) to rotate at the same speed but in different directions. When the concrete in the discharge mechanism 6 reaches 1 / 3 or more, the discharge mechanism 6 will engage with the rotating wheel 2 (536) to discharge the concrete. When the concrete in the discharge mechanism 6 is less than 1 / 3, the action of the adjusting mechanism 7 will engage with the rotating wheel 1 (537) to prevent further concrete from falling. This prevents uneven discharge due to insufficient concrete in the discharge mechanism 6.

[0061] In a preferred embodiment, the discharge mechanism 6 includes:

[0062] A fixed base 61 is fixed on the adjusting mechanism 7. A discharge device 63 is fixed on the fixed base 61. Multiple arc-shaped plates are fixed around the circumference at a 45° angle inside the discharge device 63. The arc-shaped plates form a discharge trough.

[0063] The bearing 64 has an outer ring that can slide vertically within the groove 9;

[0064] The rotating chamber 62 is rotatably mounted on the discharge device 63 at one end and fixed on the inner ring of the bearing 64 at the other end.

[0065] The fixing rod 65 is evenly fixed at one end around the circumference of the rotating chamber 62; and

[0066] The regulator 66 is fixed to the other end of the fixed rod 65 and connected to the converter 53.

[0067] It should be noted that when concrete has fallen into the rotating chamber 62 to 1 / 3 or more, the weight of the concrete will cause the fixed seat 61 to slide downwards and press against the adjusting mechanism 7, i.e., the rotating chamber 62 slides down. As the rotating chamber 62 slides down, the adjuster 66 disengages from the first rotating wheel 537 and engages with the second rotating wheel 536, causing the rotating chamber 62 to rotate counterclockwise. During the counterclockwise rotation, the discharge chute in the discharge device 63 will scrape concrete from the rotating chamber 62. The scraped concrete passes through the discharge chute and, in conjunction with the adjusting mechanism 7, completes the concrete pouring. When the concrete in the rotating chamber 62 is less than 1 / 3 full, the adjusting mechanism 7 will cause the rotating chamber 62 to slide upwards. At the same time, the adjuster 66 engages with the first rotating wheel 537 to drive the rotating chamber 62 clockwise. During the clockwise rotation, the discharge chute in the discharge device 63 will not be able to scrape concrete, and the discharge chute, arranged at a 45° angle, will inhibit the free fall of concrete during rotation. This, in conjunction with the adjusting mechanism 7, will stop the concrete from falling.

[0068] It should be noted that when concrete falls from the rotating chamber 62 through the discharge chute onto the adjusting mechanism 7 due to gravity, the force required to open the adjusting mechanism 7 will not be sufficient to complete the pouring and discharge of the concrete. When the rotating chamber 62 rotates counterclockwise, the scraping action of the discharge device 63 will increase the amount of concrete falling onto the adjusting mechanism 7, ultimately causing the adjusting mechanism 7 to open and complete the pouring and discharge. When the rotating chamber 62 rotates counterclockwise, the discharge device 63 will inhibit the concrete from falling through the discharge chute, preventing the weight of the concrete on the adjusting mechanism 7 from meeting the pouring and discharge conditions.

[0069] It should be explained that the rotating chamber 62 can only rotate by being driven by the conversion mechanism 5 during the rotation process, and will stop rotating immediately after being disengaged from the conversion mechanism 5.

[0070] In a preferred embodiment, the regulator 66 has a mating pin groove, which can be switched between the first rotating wheel 537 and the second rotating wheel 536 to achieve different rotations of the rotating chamber 62 under different working conditions.

[0071] In a preferred embodiment, the adjustment mechanism 7 includes:

[0072] A fixed housing 78 is fixed on the housing 2. A rotating base 71 is fixed on the fixed housing 78, and one end of the bevel gear set 72 is fixed through the rotating base 71.

[0073] The rotating rod 73 is fixed to the other end of the bevel gear set 72, and the rotating rod 73 is fixed with multiple pins around its circumference;

[0074] A compression spring 75 has one end fixed to the fixed housing 78 and the other end fixed to the fixed base 61. A linkage rod 76 is symmetrically fixed to one end of the linkage rod 76 through the fixed base 61. The other end of the linkage rod 76 has a threaded through hole.

[0075] A threaded rod 74 is threadedly connected to the linkage rod 76, and the threaded rod 74 has a second mating pin groove inside, which is slidably connected to the third pin; and

[0076] The pressure rod 77 is hinged to the fixed shell 78, and a torsion spring is provided at the hinge.

[0077] It should be noted that the connection between the threaded rod 74 and the rotating rod 73 allows the threaded rod 74 to slide not only on the rotating rod 73, but also, when the rotating seat 71 is rotated, the threaded rod 74 can rotate with the rotating rod 73 via the bevel gear set 72. During the rotation of the threaded rod 74, the sliding of the linkage rod 76 can be controlled. After the concrete is poured, one-third of the concrete will not be discharged. At this time, rotating the rotating seat 71 can cause the rotating chamber 62 to slide, causing it to rotate counterclockwise to discharge the remaining concrete in the chamber.

[0078] It should be noted that the weight of the concrete that falls freely onto the pressure rod 77 through the discharge device 63 will not be enough to open the pressure rod 77. Only when the rotating chamber 62 rotates counterclockwise, with the assistance of the discharge device 63, can the accumulated amount of concrete open the pressure rod 77.

[0079] In practice, the concrete is first connected to the concrete conveying pipeline via the connecting seat 1. When the concrete pouring begins, the motor 51 is started, and the screw conveyor 8 conveys the concrete and performs secondary mixing to prevent the concrete from segregating. When the concrete falls into the rotating chamber 62 and reaches 1 / 3 or more of the rotating chamber 62, the rotating chamber 62 will rotate counterclockwise under the drive of the conversion mechanism 5. The uniform pouring of concrete is completed by the adjustment mechanism 7. When the amount of concrete is less than 1 / 3, the rotating chamber 62 will rotate clockwise under the action of the compression spring 75 and the conversion mechanism 5, and the pouring and discharge of concrete will stop under the action of the adjustment mechanism 7.

[0080] It should be noted that when the concrete pouring work is completed, the rotating seat 71 should be turned in time so that the rotating chamber 62 rotates counterclockwise under the action of the conversion mechanism 5, so that the concrete in the rotating chamber 62 can be discharged in time.

[0081] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
